K = {1,2,3,4,5,6}. A function from K to K is such that for n∈K
n ↦1 if n is odd , and
n↦ n/2 if n is even
Describe this function by the set of ordered pairs.
- E = {3,4,5,…..21} and F = {2,4,6,8,10}.
A function F to E is such that n↦ n+3 for each n∈F. Find the set of ordered pairs for the
function. Write down the range.
